Types

type Glyph

type Glyph struct {
	T   *sdl.Texture
	Src *sdl.Rect

	Color  utils.ColorRGB
	Shadow bool

	Width  int
	Height int

	OffsetX int
	OffsetY int
}

Glyph represents one rendereable glyph

type RenderGlyph

type RenderGlyph struct {
	T   *sdl.Texture
	Src *sdl.Rect

	ForegroundColor utils.ColorRGBA
	BackgroundColor utils.ColorRGBA
}

RenderGlyph represents one rendereable glyph.

type Renderer

type Renderer struct {
	GlyphWidth  int
	GlyphHeight int

	OriginX int
	OriginY int
	// contains filtered or unexported fields
}

Renderer is able to render actual elements onto the correct screen positions.
